COMMONWEALTH OF PENNSYLVANIAPENNSYLVANIA PUBLIC UTILITY COMMISSIONP.O. BOX 3265, HARRISBURG, PA 17105-3265IN REPLY PLEASE REFER TO OUR FILEM2012-2313373April 16, 2015TO ALL INTERESTED PARTIES:Re:Implementation of the Alternative Energy Portfolio Standards Act of 2004: Standards for the Participation of Demand Side Management Resources – Technical Reference Manual 2015 UpdateDocket No. M-2012-2313373On December 18, 2014, the Pennsylvania Public Utility Commission (Commission) entered an Order adopting the 2015 Technical Reference Manual (TRM) update in the above-referenced matter. The TRM Annual Update Order and 2015 TRM update are posted on the Commission’s website at: this Secretarial Letter, the Commission releases Errata to the 2015 TRM. The Errata correct the following:Errors in Section 2.1.1 – ENERGY STAR Lighting. The errors are as follows:The inclusion of a 365 days-per-year (days/yr) constant in the ΔkWpeak equation for ENERGY STAR LED Bulbs (screw-in). The ΔkWpeak equation does not determine a per-year value; therefore, the 365 days/yr constant is unnecessary. Page 18 of the 2015 TRM has been updated to reflect the removal of this value.Incorrect information in Table 2-2: Baseline Wattage by Lumen Output for General Service Lamps (GSL). For the minimum-maximum lumen range of 310-449, the Wattsbase post-2020 value is listed as 25. Based on the reference provided for this table, this value should be 9. Table 2-2 on page 21 of the 2015 TRM has been updated to reflect the appropriate Wattsbase post-2020 value of 9.Errors in Section 2.2.1 – Electric HVAC [Heating, Ventilation and Air Conditioning]. The errors are as follows:An incorrect change in kilowatt-hours (ΔkWh) value for the ground source heat pump (GSHP) desuperheater measure. The ΔkWh listed in the measure is 567. However, during the 2015 TRM update, the Commission amended the temperature-of-hot-water (Thot) variable to 119 °F. This amended variable is included in the algorithm for the ΔkWh; however, the kWh savings value included in the protocol were not updated based on the amended Thot variable. The ΔkWh should be 534 using the updated variable. Page 36 has been updated to reflect the appropriate ΔkWh value.A lack of clarity regarding the applicability of the energy efficiency ratios contained in Table 2-10: Residential Electric HVAC – References. For the energy efficiency ratio of the baseline unit (EERb) and the energy efficiency ratio of the unit being installed (EERe), clarification is needed regarding what values apply to early retirement versus replacement on burnout scenarios, as well as what values apply to central air conditioning (A/C) systems. Table 2-10 on page 37 has been updated to clarify which EERb values should be used for central A/C systems and for early replacement scenarios. The table has also been updated to clarify which EERe value should be used for central A/C systems.Errors in the conversion factor used to convert watt-hours (Wh) (or its variations, such as kWh) to British thermal units (Btu) (or its variations, such as MMBtu). The conversion factor is listed as 3.413 (or other variations, such as 3,413 or 0.003413), where applicable), when it should be 3.412 (or other variations, such as 3,412 or 0.003412, where applicable). The following pages have been updated accordingly:Page 39 – 3.413 to 3.412;Page 42 – 3.413 to 3.412;Page 77 – 3.413 to 3.412;Page 91 – 3,413 to 3,412;Page 160 – 0.003413 to 0.003412;Page 161 – 0.003413 to 0.003412;Page 188 – 3.413 to 3.412;Page 190 – 3.413 to 3.412;Page 279 – 3.413 to 3.412;Page 280 – 3.413 to 3.412;Page 323 – 3.413 to 3.412; and,Page 447 – 3,413 to 3,412.An update to the default unit energy savings and default unit peak demand reduction for Section 2.3.3 – Solar Water Heaters on page 90. As noted previously, page 91 has been updated to reflect the appropriate kWh to Btu conversion factor of 3,412. This amendment, as well as the previously noted change to the Thot variable, required the recalculation of the default unit energy savings (kWh) and default unit peak demand reduction (kW) values. The summary table on page 90 has been updated to reflect the recalculated values of 1,598.8 kWh and 0.2529 kW for the default unit energy savings and default unit peak demand reduction, respectively.Inconsistencies between summary tables at the beginning of measures and the unit energy savings and unit peak demand reductions calculated within the protocol. To ensure consistency in values, the following pages have been updated to reflect the appropriate values in the summary tables:Page 32 – 10.6 kWh per strand to 20.2 kWh per strand;Page 93 – unit energy savings from 3,338 kWh/yr to 3,143 kWh/yr and unit peak demand reductions from 0.2687 kW to 0.2529 kW;Page 97 - unit energy savings from 1,734.5 kWh/yr to 1,632.9 kWh/yr and unit peak demand reductions from 0.140 kW to 0.1314 kW;Page 166 – 0.0098 kW to “varies based on capacity” as the default savings provided in Table 2 90: Dehumidifier Default Energy Savings on pages 167 and 168 provide the default kW values for various dehumidifiers based on their capacity;Page 169 – Unit energy savings updated to 47.5 kWh from 47 kWh for Cold Only ENERGY STAR Water Coolers and unit energy savings for Hot and Cold Storage and Hot and Cold On-Demand ENERGY STAR Water Coolers provided in summary table. Unit peak demand reduction value for Cold Only ENERGY STAR Water Coolers amended from 0.0232 kW to 0.00532 kW to reflect the reductions calculated within the measure. Unit peak demand reduction values for Hot and Cold Storage and Hot and Cold On-Demand ENERGY STAR Water Coolers provided in summary table. The summary table on page 169 has been updated to reflect the kWh and kW values calculated within the measure.Errors in fossil fuel consumption values in Sections 2.3.4 – Fuel Switching: Electric Resistance to Fossil Fuel Water Heater and 2.3.5 – Fuel Switching: Heat Pump Water Heater to Fossil Fuel Water Heater. As previously noted, the Commission, as part of the 2015 TRM update, amended the Thot variable to 119 °F. This variable affects the fossil fuel consumption values included within these two measures. The values in the protocol were not updated to reflect the usage of the new Thot variable. Table 2-53: Fuel Consumption for Fuel Switching, Domestic Hot Water Electric to Fossil Fuel on page 96 and Table 2-59: Gas, Oil, Propane Consumption for Heat Pump Water Heater to Fossil Fuel Water Heater on page 102 have been updated to reflect the newly-calculated values. Specifically, the fossil fuel consumption value for gas has been updated from 15.37 MMBtu to 14.47 MMBtu; the value for propane has been updated from 15.37 MMBtu to 14.47 MMBtu; and the value for oil has been updated from 20.04 MMBtu to 18.86 MMBtu. The measure summary tables on pages 93 and 97 have also been updated to reflect these new fossil fuel consumption values.Errors in Section 2.3.8 – Water Heater Pipe Insulation. The errors are as follows:As previously noted, the Commission, as part of the 2015 TRM update, amended the Thot variable to 119 °F. This variable affects the annual energy use of an electric water heater. The kWh in the protocol were not updated to reflect the usage of the new Thot variable. Page 111 has been updated to reflect the amending of the kWh from 3,338 to 3,143 and amending the kWh based on ten feet of insulation from 100.14 to 94.29. The amendment to the kWh values also requires an update to the change in kWh per year (ΔkWh/yr) value, from 10 kWh/yr per foot to 9.43 kWh/yr per foot. Page 111 has been updated to reflect this change.The amendment to the kWh/yr per foot value also requires an update to the summer peak kW savings (ΔkWpeak) per foot of installed pipe insulation value. The updated 9.43 kWh/yr per foot value is included in the calculation for ΔkWpeak per foot of installed pipe insulation. Therefore, pages 111 and 112 have been updated to reflect the newly-calculated value of 0.000759.A missing footnote on page 130. Page 130 of the 2015 TRM included a reference to footnote 132; however, this footnote was inadvertently omitted from the footer of the page. Page 130 has been amended to include footnote 132.A reference to the incorrect program year on page 141. The “UEC [Unit Energy Consumption] Equations and Default Values” section on page 141 includes language that each UEC value represents various information inputs from program year four (June 1, 2012 – May 31, 2013) data. This is incorrect. The correct year is program year five (June 1, 2013 – May 31, 2014). Page 141 has been updated to reflect the appropriate program year information.The inclusion, on page 235, of erroneous language regarding Appendix E – Lighting Audit and Design Tool for New Construction. Specifically, page 235 includes a paragraph discussing the use of Appendix E for determining the change in kW (ΔkW) based on different control strategies (SVG), hours of use (HOU), coincidence factors (CF) or interactive factors (IF). This language was inadvertently included on this page and does not accurately reflect the functionality of the Appendix E tool. Page 235 has been updated to reflect the removal of this paragraph.An error in consistency between the measure life for the ENERGY STAR LEDs [Light-Emitting Diodes] measure in Section 2.2.1 – ENERGY STAR Lighting and Appendix A – Measure Lives. The correct measure life for ENERGY STAR LEDs is that listed in Section 2.2.1, 15 years. Page 505 in Appendix A has been updated accordingly.The omission of ENERGY STAR Ceiling Fans from the Appliances End-Use section of Appendix A – Measure Lives. The ENERGY STAR Ceiling Fans measure was inadvertently omitted from Appendix A. Page 506 has been updated to include this measure in the Appliances End-Use section.This Secretarial Letter, the corrected 2015 TRM and redlined versions of all affected pages are available on the Commission’s website at the aforementioned link.24599902730500Sincerely,Rosemary Chiavetta SecretaryCC:Darren Gill, Deputy Director, TUS Joseph Sherrick, Supervisor, TUS Megan Good, Analyst, TUS Kriss Brown, Attorney, LAWSTAR indoor fluorescent fixture, ENERGY STAR outdoor fluorescent fixture, or an ENERGY STAR ceiling fan with a fluorescent light fixture.Definition of Baseline EquipmentThe baseline equipment is assumed to be a socket, fixture, torchiere, or ceiling fan with a standard or specialty incandescent light bulb(s).An adjustment to the baseline wattage for general service and specialty screw-in CFLs and LEDs is made to account for the Energy Independence and Security Act of 2007 (EISA 2007), which requires that all general service lamps and some specialty lamps between 40W and 100W meet minimum efficiency standards in terms of amount of light delivered per unit of energy consumed. The standard was phased in between January 1, 2012 and January 1, 2014. This adjustment affects any efficient lighting where the baseline condition is assumed to be a general service, standard screw-in incandescent light bulb, or specialty, screw-in incandescent lamp.For upstream buy-down, retail (time of sale), or efficiency kit programs, baseline wattages can be determined using the tables included in this protocol below. For direct install programs where wattage of the existing bulb is known, and the existing bulb was in working condition, wattage of the existing lamp removed by the program may be used in lieu of the tables below.AlgorithmsThe general form of the equation for the ENERGY STAR or other high-efficiency lighting energy savings algorithm is:Total Savings = Number of Units × Savings per UnitENERGY STAR CFL Bulbs (screw-in):?kWhyr = Watts base-WattsCFL1000 kWW ×HOU effbulb× 1+IEkWh ×365daysyr ×ISReffbulb?kWpeak = Watts base-WattsCFL1000 WkW ×CF× 1+IEkW ×ISReffbulbENERGY STAR LED Bulbs (screw-in):?kWhyr = Watts base-WattsLED1000 WkW ×HOU effbulb× 1+IEkWh ×365daysyr ×ISReffbulb?kWpeak = Watts base-WattsLED1000 WkW ×CF× 1+IEkW ×ISReffbulbVariable Input ValuesBaseline Wattage Values – General Service LampsBaseline wattage is dependent on lumens, shape of bulb, and EISA qualifications. Commonly used EISA exempt bulbs include 3-way bulbs, globes with ≥5” diameter or ≤749 lumens, and candelabra base bulbs with ≤1049 lumens. See EISA legislation for the full list of exemptions. For direct installation programs where the removed bulb is known, and the bulb is in working condition, EDCs may use the wattage of the replaced bulb in lieu of the tables below. For bulbs with lumens outside of the lumen bins provided, EDCs should use the manufacturer rated comparable wattage as the WattsBase. For EISA exempt bulbs, EDCs also have the option of using manufacturer rated comparable wattage as the WattsBase, rather than the tables below.To determine the WattsBase for General Service Lamps , follow these steps:Identify the rated lumen output of the energy efficient lighting productIdentify if the bulb is EISA exemptIn REF _Ref373137256 \h \* MERGEFORMAT Table Error!

Additionally, they typically see an overall energy savings when looking at the source energy of the electric unit versus the fossil fuel-fired unit. Federal standard electric water heaters have energy factors of 0.904 for a 50 gal unit and an ENERGY STAR gas and propane-fired water heater have an energy factor of 0.67 for a 40gal unit and 0.514 for an oil-fired 40 gal unit.EligibilityThis protocol documents the energy savings attributed to converting from a standard electric water heater to an ENERGY STAR natural gas or propane water heater with Energy Factor of 0.67 or greater and 0.514 for oil water heater. If a customer submits a rebate for a product that has applied for ENERGY STAR Certification but has not yet been certified, the savings will be counted for that product contingent upon its eventual certification as an ENERGY STAR measure. If at any point the product is rejected by ENERGY STAR, the product is then ineligible for the program and savings will not be counted.The target sector primarily consists of single-family residences. AlgorithmsThe energy savings calculation utilizes average performance data for available residential standard electric and fossil fuel-fired water heaters and typical water usage for residential homes. Because there is little electric energy associated with a fossil fuel-fired water heater, the energy savings are the full energy utilization of the electric water heater.

Standard heat pump water heaters have energy factors of 2.0 and ENERGY STAR gas and propane water heaters have an energy factor of 0.67 for a 40 gal unit and 0.514 for an oil-fired 40 gal unit.EligibilityThis protocol documents the energy savings attributed to converting from a standard heat pump water heater with Energy Factor of 2.0 or greater to an ENERGY STAR natural gas or propane water heater with Energy Factor of 0.67 or greater and 0.514 for an oil water heater. If a customer submits a rebate for a product that has applied for ENERGY STAR Certification but has not yet been certified, the savings will be counted for that product contingent upon its eventual certification as an ENERGY STAR measure. If at any point the product is rejected by ENERGY STAR, the product is then ineligible for the program and savings will not be counted.The target sector primarily consists of single-family residences.AlgorithmsThe energy savings calculation utilizes average performance data for available residential standard heat pump water heaters and fossil fuel-fired water heaters and typical water usage for residential homes. Because there is little electric energy associated with a fossil fuel-fired water heater, the energy savings are the full energy utilization of the heat pump water heater.
